One of the more valuable forms of opal, Boulder opal can exhibit many different colors making it supremely unique in style. The range of spectral colors can depend on the age and size of the stone, as well as where it's found or mined. Boulder opal is distantly related to Australia’s black opal, even though it's significantly rarer and harder to find.
Each Boulder Opal design is set in 925 sterling silver and selected for the way it carries the stone’s color, pattern, or shine into wearable jewelry. Every piece is selected to feel special without losing the practical beauty customers expect from sterling silver gemstone jewelry.
